ALOIS BEYER, OF CHICAGO, ILLINOIS.

WATCHMANS CLOCK.

To all whom it may concern:

Be it known that I, ALoIs BEYER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in VVatchmens Clocks, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to that part of the clock known as the recording mechanism and in which the record is made by a key insertible therein and the record made on a revolving` dial by a movement of the key by the operation of the mechanism with which it is in contact.

The object of my invention is to so close the keyway in said mechanism as to prevent tampering with the record dial by any means insertible in the keyway, and to prevent the making of a record except by the special key by which the mechanism in the particular clock is set for the operation of recording on the dial.

The manner in which I accomplish my object is described in the following specification and illustrated in the accompanying drawings in which:

Figure 1 is a rear elevation of part of the clock case, the back being removed to show the position of the recording mechanism and part of a record dial. Fig. 2 is a top plan view of the recording mechanism disconnected from the clock case shown in Fig. l. Fig. 3 is a rear elevation similar to Fig. 1, the top plate and dial being removed. Fig. 4 is a view similar to Fig. 3, but with the key inserted. Fig. 5 is an end view of the parts shown in Fig. 3. Fig. 6 is a view from below of the parts shown in top view in Figs. 1, 4 and 8. Fig. 7 is a view from the left of the parts shown in Fig. 3. Fig. 8 is a sectional view on the line 8 8 Fig. 5. Fig. 9 is a sectional view on the line 9-9 Fig. 6. Fig. 10 is a perspective view of the shutter. Fig. 11 is a perspective view of the guide plate. Fig. 12 is a perspective view of the double ended lever, and Fig. 13 is a view of the register key.

In the drawings, A is the clock case, circular in form, and provided with a cover not shown. This case and cover incloses the clock and recorder mechanism and pre- Specication of Letters Patent.

vents all access thereto except through a keyway hereinafter described.

B is a frame attached to the interior of the rim of the case A by the screws B1 which extend through the braces B2 into the rim A1 as shown in Fig. l. In this frame is a keyway B3 shown in Fig. 2. This aperture is encircled by a projecting ring B4 which extends through an aperture A2 in the rim A1 as shown by the dotted lines in Fig. 1. Attached to the frame B is a top plate C secured at one end by the screws C1. This plate is spaced from the frame to permit the rotation between those parts of the dial D. In that part of t-he frame covered by the dial D and plate C is a slot B5, shown in Figs. 4 and 8 and by the dotted lines in Fig. 3. This slot extends from the ring B4 to the other end of the frame B, as shown in Figs. 4 and 8, and is adapted for the insertion and movement therein of a key as shown in Fig. 4. Slidably supported on this slotted part of the frame is a shutter E shown in detail in Fig. 10, and in position on the frame in Fig. 3 over the slot B5 and locked in that position by the lip F2 of the lever F shown in detail in Fig. 12, and hereinafter described. This shutter is also shown in Fig. 4 in the open position permitting the key to be raised through the slot as hereinafter described. The end E4 of the shutter is shown in Fig'. 5, slidably secured on the frame.

Pivotally secured to the Linder side of the slotted part of the frame is a double ended lever F. One end F1 of this lever extends across the slot B5, as shown in Figs. 3 and 8. The other end of the lever extends beyond the frame and has a lip F2 and an elongated aperture F3. The lip F 2 is adapted, when the shutter E is in the position over the slot B5, to engage the part E3 of the shutter shown in Figs. 3 and 10 to lock it in that position; and also to register with the notch E5 in the shutter E and thereby permit the shutter to be moved over said lip when the lever is forced by the key into the position shown in Fig. 4.

Extending through the aperture F3 of the lever F is a spring G coiled on a rod G1 secured in the frame B, as shown in Fig. 7. One end G2 of this spring is firmly held in a notch in the frame and the free end Gg projects through the aperture in the lever F and presses against the shutter E and is adapted when moved by the lever to enter the hook EG as shown in Fig. 4l. Pivoted on the rod G1 is a shield H. The free part IIl of this shield is in contact with the free end of the spring G intermediate of said spring and an operating shaft I as shown in Fig. 9. This shaft is journaled in the frame, parallel with the slot therein and the rod G1 and is provided with an operating handle Il. That part I2 of the shaft between the bearing walls of the frame has oppositely disposed concave faces as shown in section in Fig. 9 and is thereby adapted when rotated, to engage and move the shield H and other parts hereafter to be described. Pivotally supported on a rod J secured in the frame B, parallel with the shaft I, is a key receiver K. This receiver extends from wall to wall of the frame, and the free end Kl is adapted to be engaged by the part- I2 of the shaft I as shown in F ig. 9.

Secured on the receiver by the screws K2 is a flat spring L. Une end Ll of this spring is of substantially the same length as the end K1 of the receiver K and is thereby adapted to be engaged by the concave sides of the shaft as shown in Fig. 9. The other end L2 of the spring is adapted to engage one side of an angular key as it is inserted in the keyway, and to hold it in Contact with a recessed part K3 of the receiver K. Under the opposite side of the end L2 of this spring in a position corresponding with a notch L3 therein, shown in Fig. S, is a screw stud V in the frame B as shown in Fig. 9, the purpose of which is hereinafter described.

Compressed between the end K1L of the receiver K and the frame is a coil spring M adapted to hold the receiver in normal position against a stop pin N fixed in the frame as shown in Figs. 6 and 9. Secured by the screw O on the end of the frame is a guide plate I), which is shown in perspecf tive in Fig. ll and shown in position on the frame in Fig. 5. The channel P1 of this plate is adapted to receive the part E2 of the shutter shown in Fig. l() and thereby hold the shutter in slidable position on the frame as shown in Figs. 3, 4: and 5.

1When the several parts of the recordingl mechanism are constructed as described, their positions and operation are as follows: The shutter E under pressure of the end G of the spring G in contact with the part E3 of the shutter is normally in the position shown by the dotted lines in Figs. 3 and 5, in which position it completely covers the slot B5 and is locked in that position by the lip F2 of the lever F and thus prevents the insertion of any instrument through the keyway and key slot and thereby prevents access to the dial except by means of the special key. The shutter is held in slidable cont-act with the slotted face of the frame by the end El of the shutter which slides between the end of the plate C secured by the screws C1 and by the part E2 held in the channel P1 of the guide plate P, as shown in Figs. 3 and 5. The lever F is held in a normal position to lock the shutter as shown in Figs. 3 and S, by the pressure of the free end G3 of the spring G. In this normal position the end Fl of this lever extends across the keyway beneath the slot B5 as shown, in Figs. 3 and S. The receiver K under the pressure of the spring M is held together with the end Ll of the spring L in a normal position against the stop pin N, the free end K1 being in contact with one of the concave sides of the shaft I as shown in Fig. 9, and the part H] of the shield H is held in cont-act with the opposite concave side of the shaft under pressure of the spring G. lVth the parts in these normal positions the key Q is inserted in the keyway with the recording point It in line with the slot B, as shown in Fig. 4L. As the key is advanced the end S strikes the end F1 of the lever F and presses it forward to the position shown in Fig. t. This movement of the lever F by the key forces the end G2 of the spring G into the hook fu of the shutter E and the lip F2 of the lever is moved into line with the notch E in the shutter. At the same time the notch Ul in the side U of the key registers with the notch L2 of the spring L, and the end of the screw stud V. The handle I1 is then moved to the right, the shaft I being turned thereby. This movement of the shaft acts first on the shield Il which actuates the spring G, thereby moving the end G3 in the aperture F3 of the lever F, which being engaged in the hoo r 4 0 draws the shutter from over the slot B5 as shown in Fig. t, the continued movement of the shaft then acts upon the end L1 of the spring L, thereby pressing the receiver K against the angle edge of the key forcing the point R through the slot Bi into contact with the dial D which is held by the plate C against pressure of the key, as a result of which the part R indents the face of the dial and makes a record. The pressure of the point R of the key on the dial is regulated by the strength of the spring Ll on which the shaft operates. As the shaft is rotated and the convex edge of the shaft passes the end L1 of the spring L, the receiver under pressure of the spring M moves back to its normal position. The key is forced by the end L2 of the spring 4L into the keyway within the face of the frame, the shield is free to be moved back to its normal position against the concave side of the shaft and the spring G is thereby released and forces the shutter back over the slot B5. The key being then withdrawn, the end F of the lever F is released and the pressure of the spring G in the aperture F3 forces the lever into its normal position in which it Cai rso

locks the shutter and the slot is thereby securely closed.

The keys are individualized by the location of the notch L3 in the spring L and the location of the pin V in the frame, the notch U1 in the key being made to correspond in size and position With the size and location of such pin.

The shaft I is preferably provided With ratchet mechanism not shown, so that the shaft can be rotated in but one direction for the purpose of preventing any reverse movement of the shaft against the end K1 of the receiver K When in the normal position shown in Fig. 9, and avoiding contact With the external portion of the key as shown in Fig. 4:.
